Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552694, here are decompositions:

13 + 31552681 = 31552694
73 + 31552621 = 31552694
157 + 31552537 = 31552694
307 + 31552387 = 31552694
457 + 31552237 = 31552694
487 + 31552207 = 31552694
661 + 31552033 = 31552694
757 + 31551937 = 31552694

Showing the first eight; more decompositions exist.
